## Summary of Changes Hello, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the Apache Beam RedisIO connector by introducing native support for binary key-value pairs (`PCollection<byte[], byte[]>`). Previously, RedisIO primarily handled `String, String` pairs, requiring users to manually convert binary data to strings. This change refactors the underlying implementation to use Jedis's `byte[]` API directly, providing more efficient and flexible handling of binary data. The existing `String, String` PTransforms are now built on top of these new binary-aware transforms, ensuring backward compatibility while offering a more robust solution for various data types. ### Highlights * **Binary Data Support**: Introduced new PTransforms (`ReadBytes`, `ReadKeyPatternsBytes`, `WriteBytes`, `WriteStreamsBytes`) to support `PCollection<byte[], byte[]>` for RedisIO operations, enabling native handling of binary key-value pairs. * **Refactored Core Logic**: Refactored the underlying DoFns (`ReadFn`, `WriteFn`, `WriteStreamFn`) to directly utilize the Jedis API for `byte[]` operations, improving efficiency for binary data handling. * **Backward Compatibility**: Modified existing `String, String` PTransforms (`Read`, `ReadKeyPatterns`, `Write`, `WriteStreams`) to act as wrappers around the new `byte[]` PTransforms, handling string-to-byte serialization/deserialization to maintain backward compatibility. * **Expanded Test Coverage**: Added comprehensive test cases for the newly introduced `byte[]` PTransforms to ensure correctness and functionality across various Redis commands and stream operations. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. **Click [here](https://codeassist.google/code-review/login) to enable Memory in your admin console.** <details> <summary><b>Changelog</b></summary> * **sdks/java/io/redis/src/main/java/org/apache/beam/sdk/io/redis/RedisIO.java** * Introduced `ReadBytes` PTransform for reading `KV<byte[], byte[]>` from Redis. * Added `ReadKeyPatternsBytes` PTransform for reading `KV<byte[], byte[]>` based on key patterns. * Implemented `WriteBytes` PTransform for writing `KV<byte[], byte[]>` to Redis. * Created `WriteStreamsBytes` PTransform for writing `KV<byte[], Map<byte[], byte[]>>` to Redis streams. * Refactored `Read` to internally use `ReadKeyPatternsBytes`, converting `byte[]` to `String`. * Refactored `ReadKeyPatterns` to internally use `ReadKeyPatternsBytes`, converting `byte[]` to `String`. * Refactored `Write` to internally use `WriteBytes`, converting `String` to `byte[]`. * Refactored `WriteStreams` to internally use `WriteStreamsBytes`, converting `String` to `byte[]`. * Updated `ReadFn` to process `KV<byte[], byte[]>` and use `jedis.scan` with `byte[]` cursors and results. * Modified `Reparallelize` to handle `PCollection<KV<byte[], byte[]>>`. * Updated `WriteFn` to process `KV<byte[], byte[]>` and use `byte[]` for Redis commands. * Updated `WriteStreamFn` to process `KV<byte[], Map<byte[], byte[]>>` and use `byte[]` for Redis stream commands. * Imported necessary classes for `byte[]` handling, including `StandardCharsets`, `ByteArrayCoder`, `MapElements`, `SimpleFunction`, `Longs`, and `Collectors`. * Removed `StringUtf8Coder` import. * **sdks/java/io/redis/src/test/java/org/apache/beam/sdk/io/redis/RedisIOTest.java** * Added `testReadBytes` to verify reading binary data. * Added new test cases for `RedisIO.writeBytes()` covering `SET`, `LPUSH`, `RPUSH`, `SADD`, `PFADD`, `INCRBY`, and `DECRBY` methods with binary data. * Added `testWriteStreamsBytes` to verify writing binary data to Redis streams. * Updated `testWriteWithMethodPFAddWithExpireTime` to use `RedisIO.Write.Method.PFADD` and corrected the `pttl` assertion range. * Corrected the `pttl` assertion range in `testWriteWithMethodSetWithExpiration`. * Modified `buildConstantKeyList` to be generic to support both `String` and `byte[]` keys/values. * Imported `assertArrayEquals`, `StandardCharsets`, `Collectors`, `ByteArrayCoder`, `Ints`, and `Longs` for new test cases. </details> <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
